dynamic output
Hi Guys,

i have a input file as below

Code:
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username ='xxx_yyy_aaa_01'
ORDER    BY LastRespTime DESC

The output needed is just "=" which exist before 'xxx_yyy_aaa_01'

also if the same data file as below having "in"

Code:
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username in('xxx_yyy_aaa_01')
ORDER    BY LastRespTime DESC

then the output needed is just "in"..

i want to achive the resultant dynamically either = or in based on the data.

Can this be done in single statement or using pearl scripting..

any help over here is appreciated !!

thanks,
nitin

I believe you mean Perl scripting. Smilie

Code:
$ 
$ 
$ cat file1.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username ='xxx_yyy_aaa_01'
ORDER    BY LastRespTime DESC
$ 
$ perl -lne '/^.* (.*?)[(]*.xxx_yyy_aaa_01.*$/ && print $1' file1.sql
=
$ 
$ 
$ cat file2.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username in('xxx_yyy_aaa_01')
ORDER    BY LastRespTime DESC
$ 
$ perl -lne '/^.* (.*?)[(]*.xxx_yyy_aaa_01.*$/ && print $1' file2.sql
in
$

Assume if there are space before xxx_yyy_aaa_01 , can pls provide me the perl script for this.

Code:
SEL elapsedtime ,StartTime,QueryText
FROM dbc.qry
WHERE StartTime >= '2010-03-24 20:10:08'
AND username = 'xxx_yyy_aaa_01'
ORDER BY LastRespTime DESC

or

Code:
SEL elapsedtime ,StartTime,QueryText
FROM dbc.qry

AND username in 'xxx_yyy_aaa_01'
ORDER BY LastRespTime DESC

Here are a few cases I could think of -

Code:
$
$
$ # equal-to (=) operator not followed by space
$ cat file1.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username ='xxx_yyy_aaa_01'
ORDER    BY LastRespTime DESC
$
$ perl -lne '/^(\s*\w+){2}\s*(.*?)[\s(]*.xxx_yyy_aaa_01.*$/ && print $2' file1.sql
=
$
$ # equal-to (=) operator followed by a space
$ cat file2.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username = 'xxx_yyy_aaa_01'
ORDER    BY LastRespTime DESC
$
$ perl -lne '/^(\s*\w+){2}\s*(.*?)[\s(]*.xxx_yyy_aaa_01.*$/ && print $2' file2.sql
=
$
$ # IN operator followed by bracket "(" not followed by space
$ cat file3.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username in('xxx_yyy_aaa_01')
ORDER    BY LastRespTime DESC
$
$ perl -lne '/^(\s*\w+){2}\s*(.*?)[\s(]*.xxx_yyy_aaa_01.*$/ && print $2' file3.sql
in
$
$ # IN operator followed by space followed by bracket "("
$ cat file4.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username in ('xxx_yyy_aaa_01')
ORDER    BY LastRespTime DESC
$
$ perl -lne '/^(\s*\w+){2}\s*(.*?)[\s(]*.xxx_yyy_aaa_01.*$/ && print $2' file4.sql
in
$
$ # IN operator followed by space not followed by bracket "("
$ cat file5.sql
SEL elapsedtime ,StartTime,QueryText
FROM     dbc.qry
WHERE    StartTime >= '2010-03-24 20:10:08'
        AND      username in 'xxx_yyy_aaa_01'
ORDER    BY LastRespTime DESC
$
$ perl -lne '/^(\s*\w+){2}\s*(.*?)[\s(]*.xxx_yyy_aaa_01.*$/ && print $2' file5.sql
in
$
